25.12
Along with its on-board programming mode, this LSI also has a programmer mode as a further
mode for the writing and erasing of programs and data. In programmer mode, a general-purpose
PROM programmer that supports the device types shown in table 25.15 can be used to write
programs to the on-chip ROM without any limitation.

25.13
The boot program initiated in boot mode performs serial communications using the host and on-
chip SCI_4. The serial communications interface specifications are shown below.
The boot program has three states.
1. Bit-rate-adjustment state
2. Inquiry/selection state
Target Memory MAT
User MAT
User boot MAT
In this state, the boot program adjusts the bit rate to achieve serial communications with the
host. Initiating boot mode enables starting of the boot program and entry to the bit-rate-
adjustment state. The program receives the command from the host to adjust the bit rate. After
adjusting the bit rate, the program enters the inquiry/selection state.
In this state, the boot program responds to inquiry commands from the host. The device name,
clock mode, and bit rate are selected. After selection of these settings, the program is made to
enter the programming/erasing state by the command for a transition to the
programming/erasing state. The program transfers the libraries required for erasure to the on-
chip RAM and erases the user MATs and user boot MATs before the transition.
